SEAM CLAMP.

Application filed April 4,

My invention relates to the suspension or carrying of cables, conduitsand the like upon the sides of brick or other masonry walls and consistsin a spring memberadapted to be inserted in a wall seam and theredistorted and held by friction. Such devices are commonly known to thetrade as seam anchors or clamps.

The main object of my invention is to provide a simple in Xpensivemember adapted to be inserted easily in a seam ina wall and to securelyhold a cable or the like against the wall.

An additional object of my invention is to provide means cooperatingwith such a clamp for attaching individual lines or smaller cableswithout affecting the design or use of the main clamp member.

In the accompanying drawings which illustrate my invention Figure 1 is aside elevation of a clamp applied to a wall and before the cable isinserted therein.

Figure 2 is a similar elevation of the clamp holding a cable and alsoillustrates the additional wire carrying member.

Figure 3 is a front elevation of the parts illustrated in Figure 2.

Figure 4 illustrates a modified construction.

Figure 5 illustrates the supplementary element applied to the clampshown in Figure l.

In Figure 1, A and B represent two bricks, the space C between which isnor mally filled with mortar which is removed at intervals for thereception of the seam clamp. The clamp is preferably formed of a singlestrip of material possessing some springiness and is C-shaped having aportion adapted to be inserted in the seam C, the end 1 of which portionengages the upper face of the seam and the curved part 2 of the insertedportion engages the lower face of the seam. The opposite end 1 of theclamp terminates adjacent to the out-er face of the wall and ata pointspaced vertically from the seam. It will be understood that the clamp isdistorted when in the position illustrated in Figure l and that thetendency of the clamp is to press the upper end 1 against the outer faceof the wall. When acable D is inserted between the outer end of theclamp and the wall, the clamp is further distorted and whether in theposition shown in Figure 1 or in the position shown 1924.. Serial No.704,293.

in Figure 2., it'will be seen that there is ab threepoint frictionalcontact between the clamp and the wall provided by the shape andelast-icnat-ure of the clamp.

In the preferred embodiment of my invention the clamp is formed of aflat strap, a portion of the metal of which is displaced as indicated toprovide a slot 4 and a flange 3. This construction permits, theinsertion of a screw driver E or similar tool as shown in Figure 1 forthe purpose of bending the clamp outwardlyv to permit the insertion ofthe cable D.

The supplementary elementconsists in a holding elements and securelyretains thewire F in place.

In Figure 4: I illustrate a modified construction in which the anchorconsists in a piece of wire 9 of spring material, the upper end of whichterminates in a return bend 10 adapted to be engaged by the screw-driveror other tool as shown to move the upper portion of the clamp away fromthe wall and permit the insertion of the cable.

The supplementary member 11 to be applied to clamp 9 may be either flator round and its upper end is adapted to engage the upper end of clamp9. If member 11 is flat, its upper end maybe slotted or, if round, theupper end may be flattened and perforated, or it may form a coil tosurround the clamp.

Various other modifications of my invention may be made withoutdeparting from the spirit of my invention as expressed in the appendedclaims.

I claim: I

1. A. cable or like support for insertion in a wall seam comprising aC-shaped strap of spring material, the distortion of a portion of whichfrictionally holds the strap in a wall seam, said strap being providedwith a tool receiving slot spaced from its ends, and a tool fulcrumelement adjacent said slot.

2. A cable or like support for insertion in '70 lighter strip 5, also ofspringmaterial, and

a wall seam comprising a strap of spring material adapted when distortedto provide spaced points for frictionally engaging. a wall surface and awall seam surface at an angle to each other, a portion of said strapbeing displaced to provide an opening through which a tool may beinserted and to provide arfulcrumron which said tool may be pivoted todistort said strap.

a 3. A cable or like support for insertion in a wall seam comprising astrap of spring materialadapted' whendistorted to provide three points,for frictionally-engaging a wall and wall seam surfaces which surfacesare at an angle to each other, and perforated between its endsandprovided with an integral lug adjacent its perforation to permitinser tion of a tool and provide a fulcrum therefor for furtherdistortion to receive a cable or the like between the strap and thewall. 7

4. In a cable or like support for insertion in a wall seam, a springhaving one end for insertion in the seam to be frictionally retainedtherein and having a perforated projection at a point spaced from saidend, and an element having an end for insertion in the seam and retainedby one face thereof and having its other end adapted to engage saidperforated projection whereby said element is distorted. so as to beheld in assembly with said sprin .7 5..In an article of the classdescribed, a spring member having a portion for frictionally engagingopposing sides of a wall seam and having a body projecting from saidportion to engage the exterior face of the wall, and an element belowsaid member one end of which element is adapted to be inserted in saidseam and be retained by said member portionand a face of the wall seam,and the other end of which element is adaptedto be interengaged with thebody of said member whereby said element is so as to be held inposition.

'In testimony whereof I hereunto affix my signature this 1st day ofApril, 1924.

PHILIP HOGAN.
